CHAIR.

Patented Jan. 8, 1907.

Application filed July 26, 1904. Berial No. 218,220.

To (LZZ whom t may concern:

Beit known that I, JOHN BARTA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Chairs, of which the following is a specification.

This invention relates generally to chairs, and more particularly to an improved construction of metal chair, the object being to provide an exceedingly cheap and simple construction of metal chair which shall be light, at the same time strong and durable; and anv other object of the invention is to provide a metal chair which can be folded into compact form when not in use.

With these various objects in view the invention consists in the novel features of construction and combination hereinafter fully described, and pointed out in the claims.

In the drawings forming a part of this specification, Figure l is a perspective view of metal chair constructed in accordance with my invention. Fig. 2 is an elevation of the same in a folded position. Fig. 3 is a detail sectional view taken through the seatfrarne, showing the means for locking the chair in its opened position, Fig. 4 is a detail perspective view showing the manner of connecting the braces to the rear legs. Figs. 5 and 6 are detail views showing the manner of connecting the upper ends of the front legs to the seat-frame.

In constructing a chair in accordance with my invention I preferably employ two pieces of angle-iron A of suitable weight and thickness and from which I make the rear standards of the chair, the flanges of the angle-iron being headed down at both ends, as shown at A and A2, in order to provide flat foot portions for the rear legs and also suitable finish portions of the rear standards or back-sections. The back consists of the top crossiece B and the bottom cross-piece C and t e connecting-strips D, all of said parts being made of thin metal. The seat-frame E is made of angle-iron and is hinged to the inner faces and standards A, as shown at E. The seat proper, F, is preferably made of leather and is supported upon coil-springs G, connected at their outer ends to the seatframe and at their inner ends to a niet-allie plate G, which rests directly beneath fliesenter of the seat, as most clearly shown in Figs. 2 and 3. The front legs H are also made of :es being r their lower ends, as shown at H in order to i per ends to the desde edantedfi fi provide suitable foot portions for said legs. The legs are pivotally connected at their upexterior of the ehair-frame, as shown at H2, and the forward ange of the leg is slotted, as shown at H, to receive the vertical fiange of the seat-frame when the leg is set up to support the said seat-frame, and the upper end of the forward flange of which leg is turned down, as shown at H, and is adapted to engage the under side of the horizontal flange and the seat-frame, as most clearly shown in Fi 5, thereby relievin the pi vot of a great dea of strain and providing a steady connection when the chair is opened, as shown in Fig. l.

The front legs are connected by means of a horizontal brace I, and the rear legs of the standards are connected by means of horizontal brace K, and a latch L is ivotally connected to this brace I( and is adapted to be turned up and engage the rear portion of the seat-frame when the chairis opened and which will prevent the chair being accidentally folded. The front and rear legs are braced by means of brace-bars M, pivoted at M to the exterior of the front legs and bent at their rear ends, as shown at M2, and adapted to engage the cleats M3, secured upon the rear flanges of the rear standards A. When the chair is set up, as shown in Fig. 1, all of the arts are thoroughly braced, and a steacfy well-balanced chair is provided, being constructed of thin angle-iron, and an exceedingly lightand durable chair canbe con` structed. When it is desired to fold the chair, the braces M are disengaged from the cleats M and the latch L is turned down, so as to disengage the seat-frame. The braces M are then turned down inline with the front legs, and the seat-frame is ushed upwardly and rearwardly until it ts between the fianges of the rear standards. The front legs will overlap the bottom of the seatframe, as most clearly shown in Fig. 2, and when the chair has occupy ve little space.

Having t us fully described my invention, what I claim as new, and desire to secure by Letters Patent, is`

1. A folding chair comprising legs formed of angle-irons, a seat pivotally `connecting the front and rear legs of said chair, cleats secured to the flange of the rear legs and braces pivoter] to the toved- IOO been thus folded it will v I I0y e front legs having an'1 i the cleats of the-l rear legs and lock the legs in a vertical poslegs and the cleats arranged upon the rear tion, for the purpose described. standards and adapted to be engaged by the 2.
